摘要：
A radio communication system including a control station and at least one remote station (20) is provided. The control station has a receiver for receiving radio signals, a transmitter for transmitting radio signals and a demodulator for measuring the frequency of the received signals. Responsive to a request for frequency measurement received from the receiver, the control station also has an error signal encoder to provide an error feedback signal containing the polarity and magnitude of the frequency difference for transmission by the transmitter. At least one remote station (20) has a receiver (25), a transmitter (26), a frequency controller (46), an encoder for encoding the request for frequency measurement and for actuating the transmitter (26) to transmit the request, and a decoder (34), responsive to the received error feedback signal for adjusting the frequency control.
